Titanium Powders:Production,Characteristics,



Titanium powder is a versatile metallic material valued for its unique combination of high strength, low density, corrosion resistance, and biocompatibility. As a powder, titanium facilitates advanced manufacturing techniques like metal injection molding (MIM), additive manufacturing (AM), hot isostatic pressing (HIP), and powder metallurgy (PM) pressing and sintering to create complex titanium components.

Key applications for titanium powder include aerospace components, medical implants, automotive parts, sporting equipment, chemical processing, and consumer products. This guide provides a comprehensive overview of titanium powder, including production methods, alloy compositions, characteristics, properties, specifications, applications, and global suppliers. It aims to assist engineers, product designers, and technical program managers in selecting and using Titan-Pulver.


Production of Titanium Powder

Titanium powder is produced using the following primary methods:

Verfahren zur Herstellung von Titanpulver

  • Gaszerstäubung – High pressure inert gas disintegrates molten titanium into spherical powder
  • Plasma-Zerstäubung – Titanium electrode arcs create ultrafine spherical powder
  • Hydriding/Dehydriding – Titanium hydride powder (TiO2) is dehydrided into fine powders
  • Mechanisches Fräsen – Ball milling breaks down titanium chips into irregular particles
  • Plasma-Sphäroidisierung – Irregular powder melted in plasma to produce spherical shapes

Gas atomization and mechanical milling are most common, creating spherical and angular powder shapes respectively. Additional screening, conditioning, and blending create application-specific particle size distributions.

Compositions of Titanium Powder

While commercially pure Titan-Pulver are available, most powders for industrial uses contain small amounts of alloying elements:

Common Titanium Powder Compositions

LegierungPrimäre LegierungselementeWesentliche Merkmale
CP Titanium99.5%+ TiAusgezeichnete Korrosionsbeständigkeit
Ti-6Al-4V6% Al, 4% VHigh strength, heat treatable
Ti-6Al-7Nb6% Al, 7% NbHohe Festigkeit, biokompatibel
Ti-5555% Al, 5% Mo, 5% VHeat treatable, machinable
Ti-102310% V, 2% Fe, 3% AlHigh strength, good ductility

Aluminum, vanadium, and niobium are common additions to enhance strength and workability. Trace boron, carbon, iron, and oxygen also appear.

Alloying tailors microstructure, hardness, machinability, and other properties while retaining excellent corrosion resistance.

Excellent biocompatibility and corrosion resistance drive usage in orthopedic and dental implants. The ability to tailor titanium’s properties facilitates sporting goods with specialized performance characteristics.

Specifications for Titanium Powders

Titanium powder compositions and quality are defined by various standard specifications:

Titanium Powder Standards

Selecting Titanium Powder

Key considerations for selecting titanium powder include:

  • Zusammensetzung der Legierung – Balances desired properties like strength, ductility, hardness
  • Reinheitsgrad – Affects mechanical properties and microstructure
  • Größe und Form der Partikel – Influences powder flow, density, surface finish
  • Scheinbare Dichte und Klopfdichte – Indicates compressibility and sintering response
  • Chemische Verträglichkeit – For service conditions like acids or salt water
  • Sampling procedures – Representative testing of powder lots
  • Qualitätszertifikate – ISO 9001, AS9100, etc.
  • Technisches Fachwissen from powder producer

Samples builds and prototypes help qualify new alloys and powders for a given application. Work closely with reputable suppliers to obtain well-characterized titanium powder for optimal results.



What is the benefit of plasma atomized titanium powder?

Plasma atomization produces very spherical, flowing particles typically 10-45 microns in size. This allows excellent sintered density and surface finish.

What causes titanium powder to be pyrophoric?

Pyrophoric titanium powders ignite spontaneously in air. This is caused by extremely small particle sizes below 10 microns which greatly increase surface area and reactivity. Use inert gas handling for pyrophoric powders.

How does particle shape influence titanium powder properties?

Spherical powder flows well and provides higher and more uniform density and mechanical properties. Irregular powder offers better green strength and compressibility but less predictable shrinkage.

What post-processing can improve titanium powder reuse?

Screening, milling, and thermal treatments allow reuse of off-spec powders. Plasma spheroidization converts chips and coarser particles into spherical powder feedstock.

What standards apply to additive manufacturing of titanium parts?

ASTM F3001-14 covers characterization and quality control of Ti alloy powder for AM. ASTM F2924-14 gives standard test methods for evaluating mechanical properties of AM titanium.

Can you 3D print a titanium and steel composite structure?

Yes, some metal 3D printing processes transition between titanium and stainless steel alloys within one part by precise material switching to build bimetallic components.


Titanium powder provides engineers great flexibility to build high performance components thanks to the metal’s unique properties. Careful selection of powder characteristics and close collaboration with experienced suppliers enables optimal results across many critical applications. Ongoing advances continue to expand the capabilities, quality, and cost-effectiveness of titanium powder metallurgy processes.
